Caption: The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image of Bangladesh on May 1, 2007. The low-lying nation is an alluvial delta, and therefore, is extremely prone to flooding. The Brahmaputra, Padma, and Meghna Rivers can be seen here. The Jamuna, a branch of the Brahmaputra River, arcs through the center of the scene. A branch of the Jamuna flows east into the Meghna River. In the dry season, the course of each river is clearly defined, not blurred by excess water. The image was made with infrared and visible light to increase the contrast between water and earth. In this type of image, water is black or blue, where colored with sediment. Plant-covered land is bright green, and bare earth or lightly vegetated areas are tan. Light blue and white clouds dot the scene. In the lower image, red dots mark the location of fires. Bangladesh is one of the world's most densely populated nations. As of August 3, 2007 nearly 20 million people had been displaced by monsoon flooding in Bangladesh, India, and Nepal. Some of the floods in northeastern India were visible when Aqua MODIS flew over on August 3, only three months after this image was taken (see bh5906). The intense rains of the summer monsoon typically fall between June and October.
